Description

Die Erfindung bezieht sich auf ein programmierbares Funkgerät in Verbindung mit einem System und einem Verfahren zu Test- und/oder Diagnosezwecken innerhalb des programmierbaren Funkgeräts.The invention relates to a programmable radio in conjunction with a system and method for testing and / or diagnostic purposes within the programmable radio.

Programmierbare Funkgeräte bzw. Funkgeräte auf Softwarebasis (SDR, Software defined radio) stellen mit der dritten Generation den aktuellsten Entwicklungsstand von Funkgeräten dar. In diesen Funkgeräten sind definitionsgemäß alle wesentlichen Aufgaben mittels Software realisiert, die auf einer Hardware-Einheit bzw. einem Transceiver (Sende-Empfänger), der DSPs, FPGA und/oder GPPs enthält, implementiert ist.Programmable or software-based radios (SDR, software defined radio) represent the latest development of radios with the third generation. In these radios, by definition, all essential tasks are implemented by means of software that can be used on a hardware unit or a transceiver (transmit Receiver) containing DSPs, FPGA and / or GPPs.

Die in programmierbaren Funkgeräten realisierten Funktionalitäten sind unter anderem Kalibrierung und Überwachung, sowie Bereitstellung der Bedienoberflächen und der Fernsteuerung für das Funkgerät.The functionalities realized in programmable radios include calibration and monitoring, as well as providing the user interfaces and remote control for the radio.

Neben diesen nach außen hin sichtbaren Aufgaben sind in den Funkgeräten auf Softwarebasis noch weitere Funktionalitäten implementiert, welche der internen Organisation und der Ablaufsteuerung dienen. Insbesondere weist die Software der programmierbaren Funkgeräte der dritten Generation aufgrund von international harmonisierten Architekturen gemäß dem SCA (Software Communications Architecture)-Standard eine verbesserte Portabilität auf.In addition to these externally visible tasks, the software-based radios have implemented additional functionalities that serve internal organization and process control.

Das Dokument Mitola J: "SDR Architecture Refinement for JTRS", Milcom 2000 Bd1, 22. Oktober (2000-10-22), Seiten 214-218 , lehrt ein programmierbares modulares Kommunikationssystem (Software Defined Radio, SDR). Nicht gezeigt wird in dieser Druckschrift, dass ein von einer ersten Funktionseinheit ausgehender Zugriff auf ausführbare Kommandos einer zweiten Funktionseinheit erfolgt, sowie eine Rückmeldung über einen Status des erfolgten Zugriffs vorgesehen ist, welcher von der Barrierefunktion autorisiert ist.The document Mitola J: "SDR Architecture Refinement for JTRS", Milcom 2000 Bd1, Oct. 22 (2000-10-22), pages 214-218 , teaches a Programmable Modular Communication System (Software Defined Radio, SDR). Not shown in this publication is that an outgoing from a first functional unit access to executable commands of a second functional unit, as well as a feedback on a status of the access is provided, which is authorized by the barrier function.

Die WO 2005/050357 A2 lehrt nur einen Bypass zwischen dem verschlüsselten (schwarzen) Bereich und dem unverschlüsselten (roten) Bereich eines SDR-Radios.The WO 2005/050357 A2 only teaches a bypass between the encrypted (black) area and the unencrypted (red) area of an SDR radio.

In der WO 2005/065098 A2 ist ein Verfahren und eine Vorrichtung beschrieben, welches bzw. welche eine ladbare Wellenform-Applikation gemäß des SCA-Standards (SCA, software communication architecture) für ein programmierbares Funkgerät (i.e. ein Funkgerät auf Softwarebasis; bzw. SDR, software defined radio) erstellt. Dabei ist ein Code-Generator für eine Umgebung bezüglich der zu erstellenden Wellenform-Applikation vorgesehen. Dieser Code-Generator dient dazu, die Implementierung von Modulen der administrativen Funkgerät-Software von der Implementierung der ladbaren Wellenform-Applikation zu trennen. Dafür ist eine zusätzliche Abstraktionsebene definiert, welche in die Instanzen der administrativen Module eingegliedert ist, wobei jeweils eine Instanz das Zusammenwirken über Schnittstellen zwischen den Abstraktionsebenen einer SCA-konformen Umgebung und einer Wellenform-Applikation regelt. Diese zusätzliche Abstraktionsebene gewährleistet, dass die Schnittstellen zwischen jeweils einer Wellenform-Applikation und den technischen Abstraktionsebenen nur mit Quellcode zusammenwirken, welcher mit der SCA-Architektur konform ist. Der Quellcode, welcher aus Schablonen generiert wurde, gewährleistet für die erzeugte Wellenform-Applikation bzw. Wellenformfunktion Portabilität im Hinblick auf andere SCA-konforme Plattformen bzw. Umgebungen.In the WO 2005/065098 A2 For example, there is described a method and apparatus that generates a loadable waveform application in accordance with the SCA (software communication architecture) standard for a programmable radio (ie, a software-defined radio (SDR) software). In this case, a code generator is provided for an environment with respect to the waveform application to be created. This code generator is used to separate the implementation of modules of the administrative radio software from the implementation of the loadable waveform application. For this purpose, an additional level of abstraction is defined, which is incorporated into the instances of the administrative modules, wherein in each instance one instance regulates the interaction via interfaces between the abstraction levels of an SCA-compliant environment and a waveform application. This additional level of abstraction ensures that the interfaces between each waveform application and the technical abstraction levels interact only with source code that complies with the SCA architecture. The source code, which was generated from templates, ensures portability for the generated waveform application or waveform function with respect to other SCA-compliant platforms or environments.

Von Nachteil an diesem Verfahren bzw. an dieser Vorrichtung ist, dass nicht SCA-konformer Code nicht verwendet werden kann.A disadvantage of this method or on this device is that non-SCA-compliant code can not be used.

Der Erfindung liegt die Aufgabe zu Grunde, ein Funkgerät bzw. ein System und ein darauf anwendbares Verfahren anzugeben, welches ein Test bzw. ein Diagnosewerkzeug umfasst, womit SCA-Konformität einer für das Funkgerät zu entwickelnden Software ermöglicht wird.The invention is based on the object to provide a radio or a system and a method applicable thereto, which is a test or a diagnostic tool which enables SCA compliance of a software to be developed for the radio.

Bezüglich des Funkgeräts wird die genannte Aufgabe erfindungsgemäß gelöst durch die Merkmale des Anspruchs 1. Im Hinblick auf das System bzw. das Verfahren ergibt sich eine erfindungsgemäße Lösung aus den Merkmalen der nebengeordneten Ansprüche 6 bzw. 12. Vorteilhafte Weiterbildungen des erfindungsgemäßen Funkgeräts sind Gegenstand der auf Anspruch 1 rückbezogen Unteransprüche 2 bis 5. Die vorteilhaften Weiterbildungen des in den nebengeordneten Ansprüchen 6 bzw. 12 beanspruchten Systems zum Starten von Kommandos bzw. des Verfahrens zum Austausch von beliebigen Kommandos sind Gegenstand der rückbezogenen Ansprüche 7 bis 11 bzw. 13 bis 16.With regard to the system or the method results in a solution according to the invention from the features of the independent claims 6 and 12. Advantageous developments of the radio according to the invention are the subject of Claim 1 dependent subclaims 2 to 5. The advantageous developments of the claimed in the independent claims 6 and 12 system for starting commands or the method for exchanging arbitrary commands are the subject of the dependent claims 7 to 11 and 13 to 16.

So umfasst das erfindungsgemäße programmierbare Funkgerät (SDR , Software Defined Radio) einen Transceiver (Sende-Empfänger) und zumindest eine Wellenform, die auf einen Transceiver geladen wird. Das erfindungsgemäße Funkgerät verfügt über mehrere Funktionseinheiten, welche über geeignete Schnittstellen adressierbar sind und welche mittels einer Barrierefunktion getrennt sind. Die Schnittstellen dienen auch zu Testzwecken und/oder Diagnosezwecken der in mehrere operative Schichten gegliederten Funktionseinheiten, wobei ein von einer ersten Funktionseinheit ausgehender Zugriff auf ausführbare Kommandos einer zweiten Funktionseinheit, sowie eine Rückmeldung über einen Status des erfolgten Zugriffs vorgesehen ist. Dieser Zugriff ist von der Barrierefunktion autorisiert.Thus, the inventive programmable radio device (SDR, Software Defined Radio) comprises a transceiver (transceiver) and at least one waveform that is loaded onto a transceiver. The radio according to the invention has a plurality of functional units which can be addressed via suitable interfaces and which are separated by means of a barrier function. The interfaces are also used for test purposes and / or diagnostic purposes of the functional units subdivided into several operational layers, whereby an access to executable commands of a second functional unit emanating from a first functional unit, as well as a feedback about a status of the accessed access is provided. This access is authorized by the barrier function.

Dabei ist es von Vorteil, dass mit der Schnittstelle innerhalb des erfindungsgemäßen Funkgeräts für den Entwicklungsingenieur ein Instrument zur Erzeugung von definierten Zuständen innerhalb der Wellenformfunktionalität bereitgestellt ist, was auch ein Monitoring ermöglicht. Somit ist eine einfache Nachbildung von im Standard geforderten Testszenarios möglich. Des weiteren erlaubt es die Schnittstelle innerhalb des erfindungsgemäßen Funkgeräts, dass Funktionen in der verschlüsselten Funktionseinheit von außerhalb gestartet werden können und nicht vom Sicherheitsmechanismus abgeblockt werden.It is advantageous that with the interface within the radio according to the invention for the Development engineer is provided an instrument for generating defined states within the waveform functionality, which also allows monitoring. Thus, a simple replication of required in the standard test scenarios is possible. Furthermore, the interface within the radio according to the invention allows functions in the encrypted functional unit to be started from outside and not blocked by the security mechanism.

Zudem ist es vorteilhaft, dass die Schnittstellen innerhalb des erfindungsgemäßen Funkgeräts eine Kompatibilität mit dem SCA (Software Communication Architecture) Standard aufweisen. Damit ist es einfach, sicherzustellen, dass die für das Funkgerät zu entwickelnde Software mit dem SCA-Standard konform ist, da über diese Schnittstellen Funktionen auf den unteren operativen Schichten des erfindungsgemäßen Funkgeräts, welche nicht dem SCA-Standard entsprechen, gezielt aktivierbar sind.In addition, it is advantageous that the interfaces within the radio according to the invention have a compatibility with the SCA (Software Communication Architecture) standard. This makes it easy to ensure that the software to be developed for the radio is compliant with the SCA standard, as functions on the lower operative layers of the radio according to the invention, which do not conform to the SCA standard, can be selectively activated via these interfaces.

Des weiteren ist es vorteilhaft, dass eine höhere operative Schicht der Funktionseinheiten als eine zu Testzwecken und/oder Diagnosezwecken installierbare und deinstallierbare Applikation des Funkgeräts vorgesehen ist. Dadurch ist es für den Hersteller des erfindungsgemäßen Funkgeräts möglich, diese sicherheitskritische Applikation vor der Aushändigung des erfindungsgemäßen Funkgeräts an den Kunden zu deinstallieren. Der Kunde kann somit nicht mehr gezielt die unteren operativen Schichten der Wellenform-Software für das programmierbare erfindungsgemäße Funkgerät ansprechen. Insbesondere wird dadurch verhindert, dass unverschlüsselte Daten und/oder Steuerbefehle ungehindert die Barrierefunktion passieren und somit für Dritte leicht abhörbar sind.Furthermore, it is advantageous that a higher operative layer of the functional units is provided as an installable and uninstallable for test purposes and / or diagnostic purposes application of the radio. This makes it possible for the manufacturer of the radio according to the invention to uninstall this safety-critical application before the delivery of the radio according to the invention to the customer. The customer can thus no longer specifically address the lower operative layers of the waveform software for the programmable radio according to the invention. In particular, this prevents that unencrypted data and / or control commands pass unhindered through the barrier function and thus can be easily monitored by third parties.

Die mit dem erfindungsgemäßen Funkgerät erzielten Vorteile bestehen insbesondere auch darin, dass die ausführbaren Kommandos in einem Befehlsvorrat einer unteren operativen Schicht des Funkgeräts enthalten sind.
